Research on the control of user privacy data disclosure based on blockchain Technology

Traditional control methods always have the problems of inaccurate and time-consuming control of user privacy data leakage. This paper proposes a method of user privacy data leakage control based on blockchain technology. Firstly, the asymmetric encryption algorithm in blockchain technology is selected as the basis, combined with formula bayes to calculate the conditional probability distribution, and judge the type of user privacy data. In the case of following the discrimination method of RSS, the problem of user data privacy is solved, the data security is controlled, and the leakage is prevented. Through experimental analysis, the method proposed in this paper can not only prevent user privacy data leakage in the shortest time, but also improve the accuracy of user data privacy control, which is of great significance to user information security.
